I have a Marlin 990 and the safety is near impossible to just "push" to make safe. It does engage with a tap of a tool or by rotating the button while pushing. Yes i have tried the clean and lube route to no avail. Just wondering if anyone has had a similar problem or any tips before i try any mods on my own. It's too easy to get out of the habit of putting the safety on when it's not working properly....especially for the kids.
